Chiefs HC Haley was unavailable Monday to explain the curious mix of receivers the Chiefs used and whether they would go with that combination when they spread the field in this Sunday’s game against the Eagles in Philadelphia.

Haley and the Chiefs don’t have a deep reservoir of receivers to draw from. But among those who weren’t available to Cassel on the play in question were the Chiefs’ two fastest offensive players, rookie wide receiver Quinten Lawrence and running back Jamaal Charles.

Lawrence hasn’t mastered the playbook and dropped plenty of passes during training camp. While he is clearly not ready for a major role, on one play he could have given the Raiders a deep threat to consider.

Charles was inactive against the Raiders, in effect trading places with Savage, who didn’t play in Baltimore. Charles said Monday that the coaches haven’t told him why he didn’t play against Oakland.

“I still don’t even know,” he said.

Against the Raiders, Savage replaced Charles as running back in obvious passing situations. He was one of the busiest Chiefs against Oakland, catching six passes for 43 yards and rushing three times for 26 yards.
